Problems solved by technology

These projects are often used, and when pouring concrete, formwork grout leakage is a common problem that has not been solved for many years, resulting in honeycomb pitting of the concrete structure, which not only affects the appearance of the project, but also seriously affects the quality and life of the project structure , and even cause catastrophic losses to people's lives and property. The reason for this is that the joints of the formwork are not tight, or the formwork is not firmly fixed, especially when the formwork after turnover is poured again, serious grout leakage is more likely to occur. At present, the first two have been solved, and only the latter one is still troubled by our engineers and technicians.

Abstract

The invention discloses a geometrical shape concrete formwork sealing device. The geometrical shape concrete formwork sealing device comprises a bar-shaped air bag, an air conveying pipe and a charging connector. One end of the air conveying pipe and one end of the bar-shaped air bag are bonded, and the other end of the air conveying pipe and the charging connector are in bell-and-spigot joint. The geometrical shape concrete formwork sealing device is simple and reasonable in structure, good in sealing effect and high in practicability.

Description

technical field [0001] The invention relates to the technical field of concrete engineering, in particular to a geometrically shaped concrete formwork sealing device. Background technique [0002] Concrete structures are applied to many projects, such as municipal engineering, road and bridge engineering, water conservancy engineering, housing construction engineering, ports, docks, nuclear power plants and other projects. These projects are often used, and when pouring concrete, formwork grout leakage is a common problem that has not been solved for many years, resulting in honeycomb pitting of the concrete structure, which not only affects the appearance of the project, but also seriously affects the quality and life of the project structure , and even cause catastrophic losses to people's lives and property. The reason for this is that the joints of the formwork are not tight, or the formwork is not firmly fixed, especially when the formwork after turnover is poured again...
